With Corsica Aventure, GR20 guided treks are in small groups. Our guides will immerse you in the Corsican culture, make safe decisions and give you the best trekking experience possible. Join as a solo traveller, a couple of friends, or husband and wife. There is a good mix of walkers, along with a wide range of ages. It’s a fantastic way of meeting like-minded people.To enjoy Corsica’s GR20 you need to get the right information. At Corsica Aventure, we know the GR20 trail intimately and have been walking it since 1995. We can take the hassle out of organising a GR20 hiking trip, booking GR20 accommodation, guiding you and lighten your load by transporting your luggage along the way.
